Özet
Background: This work contains the synthesis of seven new N-heterocyclic compounds bearing imidazole, benzimidazole, pyridine, and morpholine moieties.Objectives: We aimed to synthesize N-heterocyclic compounds for a more effective drug candidate to increase the amount of acetylcholine in synapses in Alzheimer's disease. All compounds were characterized by H-1 NMR, C-13 NMR, FTIR and elemental analysis. Enzyme inhibition activity of all compounds against acetylcholinesterase was investigated, which is an indirect treatment for Alzheimer's. Molecular docking was applied to estimate the binding energy of these compounds to the acetylcholinesterase.Methods:All compounds were synthesized from reactions of 2 equivalents of N-heterocyclic starting material and 1 equivalent of 4,4'-bis(chloromethyl)-1,1'-biphenyl. The inhibition parameters of IC50 and K-i were calculated by the spectrophotometric method. AutoDock4 was used to define the binding pose of the compounds.Results: K-i values were found in the range of 80.03 +/- 19.64 to 5014.98 +/- 1139.60 nM for AChE as an enzyme inhibition strategy, which is an important parameter for the treatment of neurodegenerative such as Alzheimer's disease. In this study, molecular docking is exerted to predict the binding energy of heterocyclic compounds (especially 2, 3, and 5) against acetylcholinesterase enzyme. Their docking binding energies are in good agreement with experimental findings.Conclusion: These new syntheses are drugs that can be used as AChE inhibitors in Alzheimer's disease.
